Question

xsquare - 4x + 5 (algebraic verification)​

Answer 1

Answer:

x square+ x -5x+5

x(x+1)-5 (x-1)

so the verification say equation is wrong

Answer 2

Answer:

Step-by-step explanation:

x²-4x+5

by quadratic formula

x=(-b±√(b²-4ac))/2a

 =(4±√(4²-4(1)(5)))/2

 =(4±√16-20)/2

 =(4±√-4)/2

=(4±2i)/2

x=2(2+i)/2 ;x=2(2-i)/2

x=2+i    ,x=2-i

or

x=2±i
